How to Make Pip Install to Path on Linux

How to make pip install to PATH on Linux?

Rather than messing with existing directories in PATH, consider adding the one pip installs to.

The best place to do so is ~/.profile file. You do it by adding to it the following line:

export PATH="$HOME/.local/bin:$PATH"

Install a Python package into a different directory using pip?

Use:

pip install --install-option="--prefix=$PREFIX_PATH" package_name

You might also want to use --ignore-installed to force all dependencies to be reinstalled using this new prefix. You can use --install-option to multiple times to add any of the options you can use with python setup.py install (--prefix is probably what you want, but there are a bunch more options you could use).

How to change pip installation path

You can tell pip where to install the package. Use the -t flag , that means the target directory where you want to install the package. Have have look at pip install --help

-t, --target <dir>        Install packages into <dir>. By default this will not replace existing
                          files/folders in <dir>. Use --upgrade to replace existing packages in <dir> with
                          new versions.

You can change this on permanent basis by changing the pip.ini configuration file. See this for detail: pip install path

On Unix and Mac OS X the configuration file is:

$HOME/.pip/pip.conf

On Windows, the configuration file is: %HOME%\pip\pip.ini
The %HOME% is located in

 C:\Users\Bob on windows assuming your name is Bob

You may have to create the pip.ini file when you find your pip directory. Within your pip.ini or pip.config you will then need to put (assuming your on windows) something like

[global]
target=C:\Users\<username>\Desktop

Adding installed PIP package to path automatically

setuptools, pip and easy_install don't modify the system PATH variable. The <python directory>\Scripts directory, where all of them install the script by default, is normally added to PATH by the Python installer during installation.

If the scripts folder was not added to your PATH during installation, you can fix that by running <python directory>\Tools\scripts\win_add2path.py. (See How can I find where Python is installed on Windows?)

The above sample setup.py file worked fine for me (with the Scripts directory in PATH), by the way. I tested it with

python setup.py bdist_wheel
pip install dist\foo-0.0.1-py3-none-any.whl

and

python setup.py sdist
pip install dist\foo-0.0.1.zip

pip installs packages successfully, but executables not found from command line

check your $PATH

tox has a command line mode:

audrey:tests jluc$ pip list | grep tox
tox (2.3.1)

where is it?

(edit: the 2.7 stuff doesn't matter much here, sub in any 3.x and pip's behaving pretty much the same way)

audrey:tests jluc$ which tox
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/tox

and what's in my $PATH?

audrey:tests jluc$ echo $PATH
/opt/chefdk/bin:/opt/chefdk/embedded/bin:/opt/local/bin:..../opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin...

Notice the /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin? That's what allows finding my pip-installed stuff

Now, to see where things are from Python, try doing this (substitute rosdep for tox).

$python
>>> import tox
>>> tox.__file__

that prints out:

'/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/tox/__init__.pyc'

Now, cd to the directory right above lib in the above. Do you see a bin directory? Do you see rosdep in that bin? If so try adding the bin to your $PATH.

audrey:2.7 jluc$ cd /opt/local/Library/Frameworks/Python.framework/Versions/2.7
audrey:2.7 jluc$ ls -1

output:

Headers
Python
Resources
bin
include
lib
man
share

install python package at current directory

You can use the target (t) flag of pip install to specify a target location for installation.

In use:

pip install -r requirements.txt -t /path/to/directory

to the current directory:

pip install -r requirements.txt -t .

How to change default install location for pip

According to pip documentation at

http://pip.readthedocs.org/en/stable/user_guide/#configuration

You will need to specify the default install location within a pip.ini file, which, also according to the website above is usually located as follows

On Unix and Mac OS X the configuration file is: $HOME/.pip/pip.conf

On Windows, the configuration file is: %HOME%\pip\pip.ini

The %HOME% is located in C:\Users\Bob on windows assuming your name is Bob

On linux the $HOME directory can be located by using cd ~

You may have to create the pip.ini file when you find your pip directory. Within your pip.ini or pip.config you will then need to put (assuming your on windows) something like

[global]
target=C:\Users\Bob\Desktop

Except that you would replace C:\Users\Bob\Desktop with whatever path you desire. If you are on Linux you would replace it with something like /usr/local/your/path

After saving the command would then be

pip install pandas

However, the program you install might assume it will be installed in a certain directory and might not work as a result of being installed elsewhere.
